COPY-HOLDER.

Specificationof Letters. Patent.

Patented Dec. 31, 1918.

Application filed January 24, 1916. Serial No. 73,924.

To all whom it may concern:

Be it known that 1, CHARLES ENGLERT, a citizen of the United States; andresident of Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Copy- Holders, ofwhich the following is a specification.

The present invention relates to copy holders and more particularly tothe typein which a line guide and a work holder are relatively movablefor the purpose of pointing out on the Work successive lines to becopied, an object of this invention being to provide a constructionevhich will permit the return movement of the movable part relatively tothe stationary part by mere pressure on such movable part, so that themanipulation of the shifting or operating devices .to effect the releaseof the movable part, and the pro visionof devices. for cushioning thedescent of the movable part will be eliminated. Another object of theinvention is to provide a construction which is simple in operation,inexpensive to manufacture and not liable to get out of order. A furtherobject of the invention is to provide means of simple construction forretaining the movable part in the position to which it is adjusted, andat the same time permit the said removable part to be lowered readilywithout any j arring action. A still. further object of the invention isto provide a line guide behind which the work may be quickly fitted,and.

which is quickly adjustable to conform to work of different widths.

To these and other ends,the invention consists in certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:-

Figure 1 is a front view .of a'copy holder embodying the presentimprovements;

Fig. 2 is a vertical section through the copy holder;

Fig. 3 is an enlarged plan view of the copy holder with oneend broken;away; and

Fig. .4; is an enlarged rear. view' of the upper end of the .copy'holderwith an end portion broken away.

According to this invention there is provided a supporting-frameembodying preferably a weightedbase 1 and a tubular standard 2 risingtherefrom and having its lower-end fitted in-a socket 2-'in the'base.

The upper end of this frame 2 may be closed by a cap3 provided with aneccentric opening, while, within the standard, a partition A is arrangedalso provided with an eccentric opening which is vertically below theeccentric opening in the cap 3, the walls of these two openings servingas guiding means for the work supporting-member.

The work supporting-member preferably embodies a non-circular stem 5 ofrectangular cross section operating through the cap 3 and the partition4, and carrying, at its upper end," a cross-piece 6. This cross-piece ispreferably formed from sheet metal, bent substantially into U-shape incross-section to provide a pair of parallel horizontal flanges 7 whichat their centers are provided with perforated lugs 8. Through these lugsa reduced portion. 9 on the stem at passes, the

lugs being held apart by a spacing tube 10 which surrounds the reducedportion 9. A nut 11 on the end of the reduced portion securesthecross-piece 6 to the stem 5.

With the end in view of raising the wvork support on itssupporting-frame, there may be provided a rod 12 guided at 13 011 thewalls of an opening. in the partition 4 and carrying at its upper end aclutch-member 14 which is mounted to swing on said end and is providedwith an opening 15 through which the stem 5 passes. When the stem 12 israised, it lifts the clutch-member 14: which,

in turn, by its engagement .with the stem 5,

raises the work-holder, after which the clutch-member 14 returns. tothe. Position shown in Fig. 2. Any suitable means may be employed forraisingthe rod 12, but preferably a lever 16 is pivoted at 17 to thebase 1 and provided at its forward end with a finger piece 18 and, atits rearward end, it extends through a slot in the lower end of thetubing 2, connecting pivotally at 19 with the lower end of the rod 12. Aspring 20 is arranged between said lever 16 and the base 1 to maintainthe lever 16 in an elevated positionat its fonward end, while anadjustable stop 22 passes through an arm 23 on the lever 16 in order.that its lower end may cooperate with the base 1 to adjustably limit thedepression. movement of the operating lever 16 and thereby control thefeeding movement of the work supporting-member.

For retaining the work supporting-member: in its adjusted position, two:friction grips .24? are provided for cooperating with opposite faces ofthe stem 5. These friction weights yet, at the same time, permitting thedescent ofthe work holder when pressure is applied to the latter in adownward direction. The work is held on the work holder by a workholding means comprising preferably two spring arms extending inwardlyfrom opposite ends of the cross-piece 6 and adjustable toward and fromeach other. This adjustment may be obtained by providing the spring armswith guide arms 27' forming with the spring arms substantially U-shapedmembers. These guide arms are mounted to slide on the cross-head 6 andthe latter for this purpose has flanges 28 bent from the upper and loweredges thereof at opposite ends to provide sleeves 29 in which the guidearms 27 operate.

For the purpose of holding the turned leaves of stenographers note booksor tablets, the cross-arm or head 6 may also carry two spring arms orclasps 30 extending inwardly from opposite ends of the cross-head, andthese arms may also be adjusted toward and from each other, theadjustment being effected by guide arms 31 in one piece with the springarms to form U-shaped members, the guide arms also being slidable in thesleeves '29 in the direction of the length of the cross-head 6.

It is also desirable to provide in copy holders of this character, astationary line guide past which the work is carried by the Y .workholder.

This line guide, in this instance, comprises a central backing sectlonformed from sheet metal and bent into U-form to provide upper and lowerflanges 33, the upper flange having a central lug 34 provided with aslot 35 and secured to the upper face ofv the cap 3 by screws 36 whichalso servefor securing the spring plate 24. The backing member alsocomprises two end sections 37 adjustable on the central section 32 insleeves formed by bending tongues 38 inwardly from the flanges 33 of thecentral member. Pivotally connected at 39 to each of the end sections 37are links 40 whi'h, in turn, are pivoted at 41 to a line guide member.Preferably, this line guide memher is flexible and extensible so that itmay be made to accommodate workof different widths. As illustrated it isformed of two sections 42 of thin flexible sheet metal, each having aloop 43 at its end surrounding the a other section an i each beingconne"ted with a link 40 by a pivot 41. A plate .44 with its upper edge45 deflected rearwardly is se cured by tongues 46 to the backing member32 and thus .increases the width of the backing member at the centralportion thereof so that the work will have a wide bearing at this point.

The work holder may carry a' clamping means forsecuring it to a desk ortypewriter support, and this clamping means is preferably removable andis also adapted to be attached to a number of sides of the base so thatany edge of a top of a typewriter support may be clamped. In thisinstance, the base 1 is provided with a socket 47 at its front and witha transverse socket 48 opening at opposite sides of the support. Any oneof these sockets is adapted to receivean arm 49 of a U-shaped clamp.while the other arm 50 ofsaid clamp carries an adjusting screw 51 havinga hand piece 52 and a clamping. portion 53, the clamping portion beingopposed to the bottom of the base in order to hold the latter firmly toa suitable support.

The invention will be understood from the foregoing description, but itmay be summarized as follows:

The work is secured to the cross head 6 by the oppositely extendingclamping arms 25 which are adjusted on the cross head to correspond tothe width of the .work. The depending portion of the work is introducedbetween the guide member and the backing member of the line guide byflexing the guide member laterally, the guide member also being adjustedto correspond to the width of the work. The work is raised by depressingthe lever 16 periodically and this causes the clutch member 14 tooperate upon the stem 5 of the work support. The grips 24 hold the worksupport in this adjusted position but permit the depression thereof.After one sheet of the work has beenbopied. it is thrown over thecrosshead 6 and held bv the arms 30, which are also adjusted to correspond tothe width of the work.

A work holder constructed in accordance with this invention isinexpensive to manufacture and simple in operation, the operating partsare housed so as to protect it against dust and malicious operation. Thesize of the supporting frame has been reduced to a minimum and it isthereby adapted to be arranged in a space of small compass. The workholding means which secures the work on the work support is of simple 7construction and may be easily manipulated. The line guide is of novelform and readily permits the insertion of the work therein whileeffectively pointing out the line.
